I try to replace the visual tracker part from deepsort tracker to my original TrTr tracker

Currently flow is started from a manual trigger (i.e., joystick L2), then the SSD detector in coral usb will provide the initial rect topic to my TrTr tracker to start visual tracking. Then my tracker will keep tracking the target object.

The following video records the person following motion from 73B2 to the corridor compared with the DeepSort Trackr (= SSD Detector).

The preliminary test already shows a promising result. My tracker show a better tracking performance in the dark corridor.

I will retry this following experiments several times and take a camera-ready video for you.
